Abstract
A moisture indicator employs an enzymatic reaction, a substrate and a chromogen for use in disposable diapers, sanitary napkins, surgical dressings, absorbent pads, garments, and like articles, or for use in any instance where moisture is to be detected. The moisture indicator, which is mounted, applied to, or built into the garment, diaper, pad or other article, is comprised of a chromogenic material, enzymes, such as those commonly used to test for carbohydrates in urine or other fluids, and a substrate material which will react with the selected enzyme or enzymes in the presence of moisture. The enzyme system or systems and the indicator agent or agents can be applied together to filter paper, wood strips, plastic fibrous materials, non-woven fabrics, or any absorbent materials for the purpose of subsequently verifying visually the presence of moisture.
